Our acoustics team did not stop exploring how to make it a better sounding device even when our DA8 had received overwhelming positive feedbacks, the task to perfecting the sound experience continued for years since its first introduction. Relentless efforts includes circuit and component consideration, listening, benchmarking, testing out different combinations on both hi-end home and studio equipment. The most important key aspect is listening to feedbacks from our actual users to further improve our products.

The result is the DA8 II, a refreshing high precision DAC which retains the same top notched performance as its predecessor, which furthers engage you to bring the sound experience to another level.

USB input uses customized Combo384 chip which co-designed by Italian Amanero and Yulong. It supports DSD and PCM for formats up to 32Bit/384KHz under Mac OS X, Linux and Windows.

Different USB solutions had been tried however the original Combo384 was still preferred because of its natural and smooth sound performance.

All functions are controlled by software operating system. 2.4 inch color LED display shows the status. Dimming is enabled after 5 seconds with no operation. The unit automatic saves user settings. User friendly interface provides control for 5 different filter mode and inverse phase to produce different styles. 80 steps volume adjustment for pre amplifier output to connect to powered speakers. Under pure DAC mode direct connect to power amplifier provides even better quality sounds. It bypasses the volume control circuit and turns off the power supply to headphone amplifier to work as a pure DAC.

Multi-stage digital buffer and shaping circuit can optimize the quality of digital signal. Low phase-noise high-precision crystal oscillator as master clock, bandwidth-auto-set DPLL, switchable jitter eliminator are used to lock and optimized bad signal before decoding. Signals of high quality can be by-passed to obtain better performance.
